The LAUNCHXL-F28377S kit features all the hardware and software necessary to develop applications based on the F2837xS microprocessor. The LaunchPad is based on the superset F28377S device, and easily allows users to migrate to lower cost F2837xS devices once the design needs are known. It offers an on-board JTAG emulation tool allowing direct interface to a PC for easy programming, debugging, and evaluation. In addition to JTAG emulation, the USB interface provides a UART serial connection from the F2837xS device to the host PC. Users can download an unrestricted copy of the latest version of Code Composer Studio IDE version 6 to write, download, and debug applications on the LAUNCHXL-F28377S board. The debugger is unobtrusive, allowing the user to run an application at full speed with hardware breakpoints and single stepping available while consuming no extra hardware resources. As shown in Figure 1, the LAUNCHXL-F28377S C2000 LaunchPad features include: USB debugging and programming interface via a high-speed galvanically isolated XDS100v2 emulator featuring a USB/UART connection Superset F28377S device that allows applications to easily migrate to lower cost devices Two user LEDs Device reset pushbutton Easily accessible device pins for debugging purposes or as sockets for adding customized extension boards Dual 5V quadrature encoder interfaces CAN Interface with integrated transceiver Boot selection switches C2000, Delfino, LaunchPad, Code Composer Studio are trademarks of Texas Instruments.

LAUNCHXL-F28377S Board Overview 2Kit Contents The LAUNCHXL-F28377S LaunchPad experimenter kit includes the following items: C2000 Delfino LaunchPad Board (LAUNCHXL-F28377S) Mini USB-B Cable, 0.5m Quick Start Guide 3Installation The F28377S LaunchPad is supported in Code Composer Studio. 3.1Code Composer Studio 3.1.1Download the Required Software Code Composer Studio IDE is available for free without any restriction when used with the XDS100 emulator on the C2000 LaunchPad. The software can be downloaded from the C2000 LaunchPad page at At this site, you can also download a copy of controlSUITE that includes drivers, examples, and other support software needed to get started. 3.1.2Install the Software Once downloaded, install Code Composer Studio and the controlSUITE package. 5SPRUI25AJune 2015Revised June 2015LAUNCHXL-F28377S Overview Submit Documentation Feedback Copyright 2015, Texas Instruments Incorporated Getting Started with the LAUNCHXL-F28377S 3.1.3Install the Hardware After Code Composer Studio is installed, plug the supplied USB cable into the C2000 LaunchPad board and into an available USB port on your computer. Windowswill automatically detect the hardware and ask you to install software drivers. Let Windows run a search for the drivers and automatically install them. After Windows successfully installs the drivers for the integrated XDS100v2 emulator, your LaunchPad is now ready for use. 4Getting Started with the LAUNCHXL-F28377S 4.1Getting Started The first time the LAUNCHXL-F28377S is used, a demo application automatically starts when the board is powered from a USB host. If your board does not start the demo application, try placing S1 in the following positions and resetting the board: UP - UP - DOWN. To start the demo, connect the LAUNCHXL-F28377S with the included mini-USB cable to a free USB port. The demo application starts with the LEDs flashing to show the device is active. 4.2Demo Application, ADC Sampling The LAUNCHXL-F28377S includes a pre-programmed TMS320F28377S device. When the LaunchPad is connected via USB, the demo starts with an LED flash sequence. After a few seconds the device switches into an ADC sample mode. Each second the ADC is sampled and the sample data is relayed to you. If the sample is above mid-scale (2048), the red LED will light. However, if the sample is below mid-scale the blue LED will light. In addition to the LED display, sample information is also displayed on your PC through the USB/UART connection. To view the UART information on your PC, first figure out the COM port associated with the LaunchPad. To do this in Windows, right click on My Computer and click on Properties. In the dialog box that appears, click on the Hardware tab and open Device Manager. Look for an entry under Ports (COM this is the COM number you should be using. Are you using the correct baud rate? Most, if not all, of the examples are configured for a baud rate of 115200 when the CPU is running at 200 MHz. If you have changed the PLL settings or written your own application you may have to recalculate the baud rate for your specific application. For information on how to do this, see the TMS320F2837xS Delfino Microcontrollers Technical Reference Guide (SPRUHX5). 22LAUNCHXL-F28377S OverviewSPRUI25AJune 2015Revised June 2015 Submit Documentation Feedback Copyright 2015, Texas Instruments Incorporated Revision History Revision History Changes from Original (June 2015) to A Revision .
